Zinc & copper in pond water

Post by DaveB on Sun Aug 26, 2012 12:27 am

As you are already aware and for those who are not, a recent water report at my home has revealed a 1ppm zinc level in my pond. Nothing is being detected from my purifiers. I therefore can only explain that the zinc has come from me actually adding the stuff to the pond. Probably in the form of a blanketweed treatment at the beginning of the season???.
The water report also showed a high level of total copper. Free copper is quite low. Not 100% what this means but think it is the free copper is the problem. The difference being chelated copper, which could under certain condition become free copper. Please correct me if I am wrong. Theses copper reading are coming from my tap and my purifiers are doing nothing to remove this copper

I have decided to run my RO plant rather than fit metal removal cartridges to exsisting purifiers and hope to get these levels down as quickly as possible.
My koi have been behaving well and any small wounds have been healing ok without intervention( except the sanke)However I have recently had a few cases of fin rot and fungus. Something which I can,t understand why as my system is kept meticulously clean.
I would just like to say a thanks to Mio for supporting me with this problem.
Is there a economical way to test my water for zinc % copper, possibly in the form of a test kit?
Best Regards Dave

Copper test kit here > http://www.ebay.co.uk/sch/i.html?_nkw=copper+test+kit&_sacat=0&_odkw=zinc+test+kit&_osacat=0

I cannot find a Zinc test kit other than the Photometers/Colourometer types.

Dave,

Your recent Koi Babes issues I honestly believe are a direct result of Parasites, and the subsequent Chemical onslaught as opposed to `Water` contaminants ... IMO.

RO will dilute the heavy metal values and reassure you ... Plants uptake heavy metals also.

All Species exposed to prolonged heavy metal environments produce a protective substance called MT, among others > http://en.wikipedia.org/wiki/Metallothionein

Some Copper info here > http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA347472


I`m more than Happy to help in any way I can Sweetie Very Happy

Cheers for info
I have used one of those copper kits, but don,t show low levels of copper. , only very high 0.3ppm and above, so will try the other one

Dave,

Something else worth considering ?

Fin Rot is one of the earliest indicators of STRESS across the board and the fact that you have NOT previously, in the two decades of Koi Keeping experienced this Malady to such a degree convinces me that these symptoms are not entirely water related, in that the problem began with the Parasites/Med onslaught initially.

Once depleted immunologically, heavy metal loads previously tolerated might be more difficult to acclimate to until full health is resumed once more...

My supply water is loaded with Copper at source ... I have not tested Tap/Pond values, and would not unless the Koi Babes had issues,symptoms relating to Heavy Metal Toxicity .....

I hope that reassures you Sweetie ... Wink

I apprecieate what you are saying and agree it is probably not the copper & zinc levels which have caused me problems but perhaps something has changed in the supply water.Me thinks we have had unpresidented amounts of rain this year and wonder if this has had any effect on pipe coatings. I now wonder if I am doing the right thing with RO as I am also reducing G.H. levels which binds up the free copper. One thing I do remember when last running RO the lustre and condition of the koi was very much improved.
I am not sure I will want to run the RO to the extremes of last time with d.H so low and a TDS of only 35. Perhaps I could re introduce some calcium chloride and epsom salts to give d.h level of 2d.H and maintain k.H. with bicarb also 2 d.H. Just an idea

My GH averages 3-4 dh and KH 2 Dave with a PH of 8+ throughout Summer ...

2 dh of both sounds manageable, although you might want to tweak the GH a little higher than KH if doing so stabilises PH as Mike S suggests it does Very Happy

Mio I think I will try that as I have been having problems with a p.H swing of more than 0.5 all summer with only a small amount of blanketweed. I have also been having difficulty controlling the temp due to running the heat pump 1 degree fluctuation. Perhaps these too have been contributing factors to stressing hte koi. It should be easier now to control both as daylight hours shorten and temps get lower. Best Regards dave
